Problems solved by technology

[0003] The existing geomembranes have the following problems in actual use: During the covering construction, the damage to the geomembrane is likely to be caused. The damage is generally divided into penetrating and non-penetrating, and non-penetrating is divided into upper surface damage and The lower surface is damaged, and the waterproofness of the geomembrane is greatly reduced due to the damage, which needs to be repaired in time. However, the geomembrane is generally laid on a large area, and most of them are black. The damage, especially the damage on the lower surface, is not easy to be found. There is no reinforcing material, so the repaired part is relatively fragile. Even if a material that enhances the structural strength is added to the repaired material, the material itself is not connected with the original reinforcing material, making the repaired part still relatively fragile

Abstract

The invention provides a novel geomembrane which comprises a plastic film layer made of a transparent material, and a reinforcing layer A and a reinforcing layer B are arranged in the plastic film layer; the reinforcing layer A is of a net-shaped structure formed by weaving a plurality of high-strength hoses A in a crossed mode, a rope A is arranged in each high-strength hose A, a plurality of partitions are arranged on each rope A, and the space between each rope A and the corresponding high-strength hose A is filled with dyeing matter. The reinforcing layer B is of a net-shaped structure formed by weaving a plurality of high-strength hoses B in a crossed mode, the rope B is formed by twisting high-strength fibers and fibers capable of changing color when encountering water, a plurality of partitions are arranged on the rope B, and the space between the rope B and the high-strength hoses is filled with water blocking matter. The geomembrane has a damage protection prompting function, the worker is reminded to maintain the geomembrane in time, and after repairing, the strength of the repaired position is high, and water leakage is not likely to happen in the later period.

Description

technical field [0001] The invention belongs to the technical field of geomembranes, and in particular relates to a geomembrane that is easy to find damage and easy to repair. Background technique [0002] Geomembrane is a geotechnical anti-seepage material made of plastic film as the anti-seepage base material and reinforced material (usually nylon mesh or non-woven mesh). The main mechanism is to block the leakage channel of the earth dam by the impermeability of the plastic film. With its high tensile strength and elongation, it can withstand water pressure and adapt to the deformation of the dam body. [0003] The existing geomembranes have the following problems in actual use: During the covering construction, the damage to the geomembrane is likely to be caused. The damage is generally divided into penetrating and non-penetrating, and non-penetrating is divided into upper surface damage and The lower surface is damaged, and the waterproofness of the geomembrane is gre...
